Another tropical storm named Harvey has hit the U.S., this time in Houston, Texas. The torrential downpour and floods has displaced hundreds of people, leaving them with little to no food, supplies, or shelter.

Many celebrities have come together in this time of need to help those most effected in Texas, donating thousands of dollars and using their platform to bring attention to the disaster.

Kevin Hart was one of the first people to publicly call on other celebs to start a new online challenge, #TheHurricaneHarveyReliefChallenge, and donate whatever they could to help Houston.
